Subject: [PATCH] chore: drop the liburing prerequisite, which was never used

IORingGroup issues io_uring syscalls directly rather than linking
liburing, so the package was never needed. Checked against the shipped
IORingGroup 1.0.9 assembly: its P/Invoke targets are libc,
libSystem.dylib, kernel32.dll, kernelbase.dll and ws2_32.dll. It
contains no reference to liburing and no call to io_uring_queue_init,
liburing's entry point -- only the raw io_uring_setup syscall.

Removes it from the README, from CI, and from the three places
NativeLibraryChecker asked for it (the cross-compile target text, the
apt and dnf package lists, and the ldconfig fallback map).
